hey

im trying to put together a order list for my 9k's. thanks for making the parts list btw.

one question. on the bridge resistors, they are commented as:

BR1-2: ???


do you have any part numbers/specs/any idea on what to use for them?

thanks.
taylor

They aren't bridge resistors.
They are bridge rectifiers...

Take a look here:

And this is what you need...

I've used a 250Vrms (400Vrrm) bridge (Type: Rounded WOG)

Hope this helps...


Neeeeeeeeeeeeeno

i've got most my parts from mouser in for my 9k's. i made up a parts list with exact details of cost, part number, number needed, ect. should be REALLY helpfull. but i got a couple of wrong parts (wrong size) so after i get her up and running i'll put up my text files (took a while too).

Let me know how your wiring the VR3AB Grayhill 71BD30-02-1-AJN 2deck/12pol

I've been wanting to build this but I was stumped on locating the 2.5k pot

is there a reason to not use ceramic caps(high quality of course) for most of the preamp? besides of course the coupling caps..

and how about polyester for the 2.2uf coupling caps?

 

[Svart]

and where are you getting the switches for the gain??

 

[jeroddumas]

I just used the cheap alpha switch available at mouser.

 

[Svart]

12$ cheap?? jeeze

:green:

I just start for 9K and i have some problems.
1.What is the value of C63? It's not in part list and schematics.
2. How many Voltage for 4x100u on Line out PCB?

Thank you so much.. :grin:

 

[asm]

i've been instructed to use just a 100nf for the c63, but theres another one thats not on the bom too, its also a 100nf, i think its the one next to the 'gain b' and to the right of the +15 and a bit higher.



i used 63v on the line out elec.

Thanks a lot ASM.... :thumb:

no problem! if you are planning to order from Mouser, let me know, cause i have a BOM with part numbers, ect for it.

PM send! I'll try and combine all the infomation into one PDF (with peoples permission) - Keith's schems & layouts, Neeno's stuffed boards for reference, PRR's Gain switch values and sketches and info on using the two power supplies (15v & 18v). Perhaps a pad/48v/phase layout too?


this is a great starting project for people new to DIY so keeping all the info in one place would make it much easier... agreeded?

Hi sammas,
that's great ! and maybe a webpage with all the collected informations about the ssl9k can be a good idea...

I can do that... just send me all the collected material and i'll try to do it.
